APPENDIX D: AIR TEMPERATURE
The graphs shown on the following pages represent the air temperature regimes at
Anchorage, Kenai, Homer, and Kodiak, Alaska, for each month of the year. The data
were assembled and summarized specifically for this project by the Air Force Combat
Climatology Center as described in Section 6.1 (Source and Description of Climato-
logical Data for Cook Inlet). The first graph shown for each month is a cumulative
percent frequency distribution of air temperatures equal to or less than the temperature
shown on the horizontal axis for all observations throughout the period of record, Jan.
1973Dec. 1997 (except Jan. 1973Oct. 1997 for Homer). The values in the upper left
corner of the graph are the POR extreme maximum and minimum air temperatures, the
mean monthly maximum and minimum temperatures, and the total number of observa-
tions comprising that month's distribution of temperatures. The second graph (in bar-
chart form) shows the mean air temperature associated with winds from each compass
direction and for calm winds.
